摘要

我们进一步研究了J/ψ→ωpp

ψ(2S)→γpp衰变末态pp在阈值附近的实验现象.发现通过考虑末态N相互作用可以同时很好地解释J/ψ→γpp

e~+e~-→pp末态阈值附近pp的分布情况

pp→pp阈值附近的散射截面

J/ψ→ωpp在阈值附近没有增强的现象

以及ψ(2S)→γpp在阈值附近不十分明显增强的现象.

Abstract

We further studied the pp near threshold phenomena in J/ψ → ωpp

ψ(2S) → γpp.We find that with the final state interactions between N we can well describe the near threshold enhancement observed in J/ψ → γpp and e+e-→ pp

the near threshold pp → pp cross section data

the no enhancement in J/ψ → ωpp and the no significant enhancement in ψ(2S) → γpp simultaneously.
